a-d - Worker ovary activation in mixed species colonies of Temnothorax ants. Number of workers per colony with activated ovaries. Minimum and maximum (horizontal lines), first and third quartiles (rectangle), and the median (dot) are shown. The total number of colonies and the number of colonies with at least one worker with activated ovaries in each group is given in parentheses. P-values are from two-sample permutation tests (*p < 0.01; **p < 0.0001; n.s. nonsignificant). After Bonferroni's correction, p-values of < 0.01 are significant at the 0.05 level. 1a. T. nylanderi workers in colonies with a T. nylanderi queen (NN, control), T. crassispinus queen (CN), T. unifasciatus queen (UN), T. recedens queen (RN) and in colonies without a queen (ØN). 1b. T. crassispinus workers in colonies with a T. crassispinus queen (CC, control), T. nylanderi queen (NC), T. unifasciatus queen (UC), T. recedens queen (RC) and in colonies without a queen (ØC). 1c. T. unifasciatus workers in colonies with a T. unifasciatus queen (UU, control), T. nylanderi queen (NU), T. crassispinus queen (CU), T. recedens queen (RU) and in colonies without a queen (ØU). 1d. T. recedens workers in colonies with a T. recedens queen (RR, control), T. nylanderi queen (NR), T. crassispinus queen (CR), T. unifasciatus queen (UR) and in colonies without a queen (ØR).
